Ultra-High Purity Silica Aerogel Block | The 0.0146 W/(m·K) Laboratory Standard for Thermal Nanotechnology

High-Purity Silica Aerogel Blocks | "Solid Smoke" for R&D

The Quantum Frontier of Thermal Isolation:
In the pursuit of zero thermal leakage, the Silica Aerogel Block is the ultimate material. We view these not as mere products, but as physical manifestations of advanced thermodynamics. By strictly maintaining the average pore size below 20nm, our manufacturing process eliminates the mean free path of air molecules, effectively neutralizing gaseous conduction to achieve a stable 0.0146 W/(m·K).

Key Technical Data (Lab Verified):

• Thermal Conductivity: 0.0146 W/(m·K) (at 25°C) — Near-vacuum level insulation.
• Pore Size Distribution: 10 - 25 nm — Monodisperse nanopore matrix.
• Porosity Rate: 95% - 99% — The world's lowest density solid material.
• Specific Surface Area: 600 - 850 m²/g — Optimized for molecular adsorption.
• Hydrophobicity: Contact Angle ≥ 150° — Extreme water repellency.
• Service Temperature: -200°C to +650°C — Stable in cryogenic vacuum environments.

Why Woqin Leads (The Supercritical Process):

• Supercritical CO2 Extraction: We operate above the critical point of CO2 to eliminate liquid-gas surface tension. This prevents capillary pressure from crushing the delicate nanoporous skeleton, resulting in a pristine block known as "Solid Smoke."
• Quantum Protection: Designed to protect sensitive superconducting qubits and cryogenic sensors from external thermal noise.
• Optical Grade: High-purity precursors allow for Refractive Indices between 1.02 - 1.05, making it suitable for Cherenkov radiators.

Advanced Research Applications:

• Cryogenic Physics: Liquid Hydrogen/Helium storage analysis.
• Aerospace Modeling: Simulating thermal protection systems (TPS) for re-entry vehicles.
• High-Energy Physics: Target material for particle detection and Laser experiments.
• Quantum Computing: Thermal management for superconducting environments.

⚠️ Handling & Logistics (Crucial):

• Fragility Warning: Pure aerogel blocks are brittle. We employ Precision CNC Slicing to provide lab-ready samples (50x50mm or 100x100mm) with ±0.2mm tolerance.
• Secure Packaging: Each block is suspended in a custom-molded, vibration-dampening polymer casing within a reinforced outer shell to minimize the risk of micro-fractures during international transit.
